Killing Groups

[Lt. Ketch]

I've been bouncing this idea around my head for while and was curious if anybody and any information on historial groups that fit this discription, or what would make up a good group.

The idea is basicly a mobile combined arms group roughly the size of a company or smaller designed to move quickly about the battlefield wither in flanking manuevers or to support a larger assult group. It would be an indpendent group from the rest of the battalion and would incorperate tanks, mech infantry and SP Artillary.

My first thought was of having:
HQ
2 AFV sections (Fast moving MBTs, or well armered light tanks)
1 platoon infantry with transport (perferribly HT or APC)
1 section of scout units (AC or scouts with transport)
1 section SP Artillary (SP mortars or ~100mm i.e. Priest/Wespe)
The commander of the of the group could also double as a AO for the SP Artillary

Any thoughts, or am I just over thinking combined arms?
